Android Smartphones question..

[Bash_Man]

I kind of in the same ship as you are. I primary my Z10 and since an Android was going to be a secondary phone for me, I chose something cheap.
I believe at the 320$ mark outright. So I went with a Nexus 4. Most of everything is on my BB10: Music, apps, communication. And on my N4, I just keep some apps I'm too lazy to sideload and game choices.

I would wait for the Nexus 5. I won't ditch my Z10 any time soon though. Or personal other choice would be a Xperia Z because, waterproof.
As for size, I don't think any of the flagships feels "right" in your hands. Nexus 4 is a little bigger than Z10 and feels slightly fragile because of the uber thin plastic? back.

thanks Chanlion. Not gonna ditch my Z10 anytime soon until I know for a fact that it wont be supported after BB is taken over/sold. I think the Nexus sounds like right up my alley as far as features/Specs (minus SD Card). i may also look into the Galaxy S4 mini.
